I lock my frames at 30 because it gives the most stutter free results. I appoligize if this has been brought up, but saw this article on AVSIM. Cpt_Piett posted a video showing how using Nvidia’s “Maximum Framerate” setting improves FrameTimes.
FrameTimes have definitely improved. Since I use Tobii & FaceTrackNoIR, I put motion blur on “Ultra” and it makes looking around smooth too.
